IMPROVEMENT IN SHINGLEv-MACHINE.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom it may concern:

Be lit .known that I, ASA'NEWELL, of Jordan, in the county of Onondaga,and State of New York, have invented a new and improved Shingle-Machine;and I do hereby declare that the following is a` full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specication, in *whichi Figure 1 is a side view ofmy invention, and

Figure 2 is a vertical longitudinal section of the same.

Similar letters of reference indicate like parts.

My invention consists- First, in so arranging two froes as to act onopposite ends ofthe bolt.

Secondly, in the arrangement of automatically-operated shaving-knivesand feed-rollers with relation to the froes.

Thirdly, in the arrangement of a table, which supports the bolt, and isautomatically elevated and depressed by the action of wedgesoperated bymeans of the free-carrier.,

Fourthly, in the arrangement of a fixed stop with relation to the froesand adjustable table.

Lastly, in the arrangement, with relation to the froes, feed-rollers,and knives, of gearing, and mechanism for operating the same, all ashereinafter set forth.

In the accompanying drawings- A is a movable table,"or bed, on which theshinglebolt is laid for living;

Y Bis the main froe, or riving-knife;

c c, fig. 2, are the shaving-knives; and

D l) are rollers, for drawing the shingles through said shaving-knives cc.

The shingle-bolt is placed upon the'table A, and the froe B is thrownforward, by' a pair of side-levers, G, and whenthe froehas out a shinglefrom the bottom of the bolt, the free then passes onward under thebolt-holder, or rest H, and the table A and the riven shingle are thenelevated by the wedges I a, g. 2, so that on the return of the froe B,its rear side catches the shingle, and pushes it to the shavingknives cc, until the rollers D D are enabled to seize the shingle and relievethe froe in the duty of passing the shingle through the shaving-knives.

As soon as the froe has reached the backward termination of its stroke,as shown in the drawings, the table A again falls, and drops theshingle-bolt, to the thickness of a shingle, below the edge of the froeB, and as the froe advances, another shingle is cut from the lower sideof the bolt, and the froe again passes under the rest H, until the tableA is elevated so that the back of the froe can catch the severed shingleand push it to the shaving-knives, and the second shingle is made; andso the operation continues.

The table A is elevated and depressed by wedges, I a I a, iig. 2, thewedges a beingl fixed to the lower side of the table, while the wedges II have a sliding movement, and are operated by tappets, on the lowersides of the slides J, which carry the froe B,'said tap,- pets engagingwith arms t', iig. l, projecting from the wedges I, through slots in theside ofthe machine.

To prevent the out ofthe main froe B from running out toward theopposite end of the Shingle-bolt so much as to present the grain of thewood unfairly to the froe, by the first end of the bolt being cut awaytoo fast with relation to its opposite end, a second froe, b, is added,which cuts into the opposite endl of the bolt for a short distance, andthen retreats before the advance ofthe main froe.

This secondary froe b -is driven by a pair yof sidelevers, g, andslides, j, in a manner similar to that of themain froe,'but makes twostrokes to one of the main froe, so that both froes are free from theshingle-bolt when the table A is raised or lowered, and at the same timeallow the main froe to advance beyond the shingle, and push it to theshaving-knives c c. v

`The rest H is for holding the shingle-bolt in place, and is constructedin such manner that the froes may pass under or beyond it, as shown ing. 2.

The lower feed-roller, I), runs in iiXed bearings, but the bearings ofthe upper roller, D', rest in boxes K, which slide vertically in theframe-work, so that the said feed-rollers accommodate themselves to thevariable thickness or taper of the shingles. v

The boxes K are pressed down by spiral springs, k, and give thefeed-rollers their elastic gripe on the shingles as they are passedthrough them.

The shaving-knives c c are set in movable boxes, C C', which have avertically-sliding movement, to give the tapering shaving-cut totheshingles.

These boxes C C are operated by cams on the main shaft, E, fig. 2, theboxes ofthe lower knife c making connection with shaft E by cam-rods,e,- ig. 2, on thel inside of the machine, and the boxes C', of the upperknife, make connection with the cam-shaft by camrods m, fig. 1, passingdown on the outside4 ofthe machine or frame-work.

The feed-rollers D are connected together at one end by matched gears t.

The driving-power is applied to the main shaft E,

`and the various devices and instrumentalities are so connected, bymeans of gears N F S R, connectingrods f r, and cam-n1ovements E e, thatall the move ments are timed with relation to each other, and act inconcert. I

By these means, I produce by machinery the superior quality of shinglemade heretofore by hand-work only, and known as the shaved shingle.

I am aware that shaving-knives4 have been used in connection withfeed-rollers; I am further aware that the upper knife has been operatedto and from the lower stationary knife, by means of a peculiarconnection with a horizontal shaft; but I am not aware that both kniveshave been thus operated, and unless both knives are operated, the taperof the shingle cannot be followed. Therefore, I do not claim theshavingknives when the upper one only is movable. Having thus describedmy invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. 'lhe froes B b', acting in concert with each other, and upon oppositeends of the bolt, when operated by the means and in the mannerdescribed.

2. The arrangement herein described of the froe B, shaving-knives c c,and feed-rollers D D', when all the parts are constructed to operate asherein set forth.

3. In a shingle-machine, the arrangement of the table A, With the iixedwedges a, and the connected slid-` ing wedges It' I i, when operatedautomatically, by means of the reciprocating carrier J, all operatingsubstantially as herein set forth.

4. The arrangementof the fixed stop H, constructed as described, withrelation to the froes B b', and automatically-adjustable table A, all asherein set forth.

5. The arrangement of the arms g g G Gr, gear-wheels N F R S t,connectionsf ll', and sha-ft E, with relation to the froes B b,feed-rollers, and shaving-knives, substantially as herein described.

The above specification of my invention signed by me, this 4th day ofNovember, 1868.

ASA NEWELL. Witnesses:
